Abstract
Abstract A remote controlled scale system which accepts control signals that are introduced over a long cable. A multiplicity of different circuits are connected to a corresponding number of AND gates. The AND gates are each provided with inputs from a series of binaries, which receive the control signals from the cable. The binaries have output circuits that are connected to the AND gates in such a way that for each of the possible combinations of the individual states of the binaries there will be only one of the AND gates that is provided with enable signals on all of its inputs. This permits remote selection and change to any one of the scales, as desired.
